Yes, The manifold holes in the head didn't line up. The reason for this is CHI designs their heads only to take their CHI manifold. In short busted a bolt trying to get a manifold on. Too much side pressure.
CHI has since moved the manifold bolts to the stock positioning till their manifold is released. Problem solved. My issue was solved by elongating the manifold holes.
Only other issue I had was fitting my 2v pacemaker 4070 4-1 extractors. They were required to be bent down 10mm. If I'd purchased 4v pacemaker 4075 4-1 extractors this wouldn't have been an issue.
I just wanted to use my close enough to new parts. So it made it difficult. Everything else went like clock work
